hwmon: (f71882fg) Add support for the F71858F
Add support for the hwmon part of the Fintek F71858FG superio IC to the f71882fg driver. Many thanks to Jelle de Jong for lending me a motherboard with this superio on it. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
